LIQUID-SPRAYEB,

Specification of Letters Patent. Patented NOV. 30, 1 915.

Application filed September 8, 1913. Serial No. 788,557.

To all whom it may concern:

Be it known that I, LEWIS AUeUsTUs As- PINWALL, a citizen of the United States, residing at Jackson, in the county of Jackson andState of h iichigan, have invented an Improvement in Liquidfiprayers, of which the following is a specification.

My present invention relates to a liquid sprayer, and the apparatus made in accordance therewith is an improvement in liquid sprayer machines, shown and described in Letters Patent No. 653,333, July 10, 1900, and No. 828,175, August 7, 1906, both granted to the Aspinwall Manufacturing Company, as my assignee.

The improvements in my present sprayer relate more particularly to the manner inwhich the barrel or receptacle is-inounted in the machine, the particular manner in which the spraying nozzles are mounted and operated, and also to an indicator device, by means of which the operator may determine when the barrel or liquid receptacle is.

empty, and these novel features of the invention will be hereinafter more particularly described.

The apparatus made in accordance with my present invention also includes anew pump construction, shown and described inmy co-pending application, Serial No.

788,558, filed September 8, 1913, for an improvement in pumps, and it also includes a novel relief valve shown and described in Letters Patent No. 1,133,785, grantedldarch so, 1915.

In the drawing, Figure lis a plan view of my improved liquid sprayer. Fig. 2 is a side elevation thereof showing one of the wheels partly broken away for more clearly illustrating the apparatus, and Fig. 3 is a sectional elevation of the barrel or liquid receptacle showing the manner in which the same is mounted and the parts immediately associated therewith, and is made on an erilarged scale.

Referring to the drawing, my improved liquid sprayer preferably includes traction wheels 10, as commonly employed, which are mounted on ashaftor axle 11. Secured on the shaft 11 immediately on the inner side of each traction wheel, a ratchet 12 is'fixed. Each ratchet 12 is engagedby a pawl 13,

which is maintained incontact therewith by a spring 14, and as is clearly shown in Fig.

ratchet by means of a hook 15 secured to a bracket plate 16 fixed on each wheel. It will be understood that by means of the ratchets 12 and pawls 13 the shaft 11 is caused to turn with the traction wheels 10. Mountedon the shaft 11 I employ a sleeve 17. In suitably spaced positions, this sleeve 17 is provided with flanges 18 and 19. A support plate 20 is secured on the flange 18 by bolts 22 or otherwise, and a support plate 21 is secured on the flange 19 in a similar, manner. The barrel indicated at 24 is supported upon the plates 20 and 21, and is secured thereto by means of bolts 23 or otherwise. This construction, as will be understood, securely fixes the barrel in position immediately above the shaft 11 and in alinement therewith. The sleeve 17 is also provided with a flange 25, adapted to receive a support and pump bed 26, which is secured I thereto by bolts 27 or in any other suitable manner. A bracket 28, which forms part of, the support plate 20, is securedto the sleeve 17 and extends forwardly herefrom. Similarly, a bracket 29 forms'part of the support plate 21 and is connected to the sleeve 17, and extends forwardly. 30 also indicates a bracket which is secured to the pump bed by the bolts 31 and 32, and this bracket, like the brackets 28 and 29, extends forwardly.

33 and 34 designate shafts which are employed, as is customary, in drawing the apparatus. i

35 is a cross piece which, adjacent one end, is connected to the shaft 33 and the forward end of the bracket 28 by means of the its opposite end, the cross piece 43 is connected to the shaft 34 by means of abracket 47 and the bolts 48 and 49. The rear end .of the shaft 33 isalso connected to one end of the barrel by means of a brace 50, and the rear end of the shaft 34 is secured to the pump bed by a brace 51.

The pump employed in my present liquid sprayer preferably comprises a vertical cylinder 52 secured to the pump bed bybolts 53, a horizontal cylinder 51 secured to the pump bed byv bolts and anrintermediate member 56 placed and secured between the adjacent ends of the said cylinders. In the pump bed bearings 57 are provided for a shaft 58, having a crank 59.

60 indicates a connecting rod, which at one end is secured to the crank 59 and at its opposite end ispivotally connected to 'one end of a beam 61which, at its opposite end, is pivotally connected to a link (32, the other end of this link being pivotally con nected to the upper end of a standard 63 suitably secured on the horizontal cylinder of the pump, the beam filbeing connected to the piston bar 61 of the horizontal cylinder.

65 is a connecting rod pivotally secured at one end to a projection on the connecting rod 60, and which is pivotally connected at its opposite end to one end of a beam 615, the other end of which is pivotally connected to one end of a link 67, which, at its other end, is pivotally connected in the standard 63, the beam (36 being connected to the piston bar 68 of the vertical cylinder 52 of the pump. The suction connection 69 of the pump is in the intermediate member 56 and may be fitted with a stand pipe 70. Also secured on the intermediate member is an air or pressure cylinder 71, in the lower end of which discharge'openings 72 and 73 are provided.

The crank shaft is fitted with the sprocket 71 and is driven by means of a chain 76 passing over this sprocket as well as over a sprocket 75 fixed on the shaft 11, so that the pump is driven by the revolution ofthe traction wheels, and I may also employ a guard 77 suitably secured in position and extending over the sprockets '71 and 75 and the chain 76 passing around the same. This pump construction is more specifically described in a separate application, which as hereinbefore stated, is made under like date herewith.

By reference to Figs. 1 and 8, itwill also be seen that I prefer to employ a relief valve 78located within the barrel 2 1. This relief valve is connected by a pipe 79, extending through one head of the barrel, to the suction 73 of the pump, and is operated by a stem 80 extending through a hole in the bar rel and pivotally connected to a lever 81, to which one end of a spring 82 is secured,.the opposite end of which is connected to an adjusting screw 83, passing through a bracket 85, and being provided with a thumb nut 84 for determining the position of the adjusting screw and regulatingthe tension on the spring. The details of construction of this relief valve are more fully described in a separate application, made under like date, as hereinbefore stated.

of the bolts 96.

Suitably secured to the outer surface of the barrel is a seat bracket 86 to which is coimected the seat- 87, and in the upper portion of the body of the barrel, 1 provide an opening 88 fitted with a cover 89 which normally rests upon a support 90. lVithin the barrel, as in my previous Sprayers, I employ an agitator or paddle 91, which at its upper end secured to a cross piece 92 by a bolt 93 or otherwise, and the cross piece is suitably connected to a rod 91 mounted in bearings provided therefor. The cross piece 92 is provided with an arm 95, to which an arm 97 is connected by means A link 98 is connected at one end to the free end of the arm 97 by means of an eye 99 and interlocked with an eye 100. The opposite or lower end of the link 98 is pivotally connected by means of a wooden connecting rod to the pin 101 on a crank 102 on one end of the shaft 58, by means of which, as will be understood, by the revolution of the shaft 58, the agitator is given an oscillating movement, and contracting with the strainer 103, acts to prevent the apertures in the strainer from becoming clogged. The strainer 103 is connected by a pipe 101 to the stand pipe and thence to the suction of the pump.

Secured centrally to the outer surface of the cross )iece 1-3 is a bracket 105, which may be fixed in position by the bolts 106 or otherwise. This bracket 105 extends rearwardly from the cross piece 413 and at its free end is provided with bearings for a rocker shaft 107 which is placed vertically and extends downwardly from the bracket. On its upper end, a foot piece 108 is attached to the rocker shaft 10'? and adjacent its lower end a plate 109 is fixed to this rocker shaft. Pivotally connected in the said shaft 109 are rods 110 and 111, which extend in opposite substantially horizontal positions therefrom.

At the left-hand side of the machine, as

shown in Fig. 1, I employ an arm 112. At one end, this arm 112 is pivotally connected to the bracket 30 by means of a bolt 114. The opposite end 113 of this arm 112 is bent at right angles thereto and extends outwardly from the machine.

115 designates a hanger which is provided with a series of openings 116, through any one of which the hanger may be secured to the shaft 34 by means of a bolt 117, and the arm 112 is pivotally connected to the hanger 115, asindicated at 119, so that by the verti- 'al adjustment of the hanger 115 the elevation of the out-turned end 113 of the arm 112 may be regulated.

120 designates a threeway connection. This is provided with a flange 121, having an opening therein through which the outturned end 113 of the arm 112 is passed, so that this three-way connection is adjustable to position laterally of the machine on this end 113 of the arm 112, and maybe fixed in any desired position thereon by means of a suitable set screw. Secured to the under side of the three-wayfconnection is a support bar 122. Adjacent its ends, this support bar isprovided with a series of apertures 123 and 124. Pivotally connectedby a bolt or other similar means, a lever 125 is secured in any one of the apertures 123, and similarly a lever 126 may be secured in any one-of the apertures 124. A nozzle 127 is pivotally connected, as indicated at 128, in a lug depending from the lever 125, and similarly a nozzle 129 is connected to the'lever 126. A connecting rod 130 extends between the forward ends of the levers 125 and 126 and is 'pivotally connected at one end in the lever 126 and adjustably connected to the corresponding end of the lever 125 by passing through a pin 131 therein. A hose pipe 132 connects the nozzle 127 with the threeway connection 120 and a hose pipe 133 connects the nozzle-129 with the three-way connection 120. A hose pipe 134 connects the three-way connection 120 with a T-connection 135, it being understood that the hose pipes 132, 133 and 134 are flexible. The T- connection 135 is connected to the discharge 72 of the pump by means of a pipe 136.

The members hereinbefore last described are duplicated on the opposite side of the machine, and comprise an arm 137, which at one end is pivotally connected to the bracket 28 and at its opposite end is outturned and indicated by 138. The pivotal connection by which the arm 137 is secured V to the bracket 28 is indicated at 139.

A hanger 140 is secured to and depends from the shaft 33 and is provided with aseries of openings through anyone of which and the shaft 33 a bolt 142 maybe passed to determine the vertical position of the hanger. This hanger, adjacent its lower end, is pivotally connected to the arm 137. in amanner similar to that in which the hanger 115 is connected to the arm 112.

143 indicates a second three-way connection, which is provided with a flange 144 having an openingtherein to receive the;

end 138 of the arm 137 and on which this three-way connection is adjustable to position, and in which it may be secured by a set screw or otherwise.

Secured. to the under side of the three-way connection, 143 is a support bar 145, prov vided, adjacent its -ends,- with a series of openings indicated at 146 and 147.

148 and 149 are levers which are connected.

sprayingnozzle 151. A connecting rod 152 extends between the opposite ends of the levers 148 andl49 and adjustablyconnected tion 135. The outer end of the rod 110 is pivotally connected to the lever 126, and similarly the outer end of therod 111 is pivotally connected to the lever 148, so that by a movement impartedto'the foot piece 108, the shaft 107 may be rocked or turned to swin the plate 109, and through the rods 110 and 111 move the levers 126 and 148, the movement of which, as will be understood, is transmitted throu h the connecting rods 130 and152to the levers 125 and 149 respec tively, so thatthe nozzles remain in alinement, that is, in'parallel positions, and the direction of the same may be varied at the will of the operator, as is also true in re.- gard to the height of the nozzles, the latter being ,adjusted through the hangers 115 and 140, and the arms 112 and 137.

Depending upon the cross piece 43 is a hanger .159, in which, adjacent to one end, adraft bar is connected by a bolt 161 through one of a'series of poles as required to equalize the draft, the inner end of the draft bar being similarly connected to a bracket depending from the cross piece The outer or forwardend of the draft bar 160'is fitted with a clevis 162, to which, as is customary, a whiflie-tree 163 is secured, the ends of the Whittle-tree being provided with hooks 164 by means of which, as is also customary," the traces may be attached.

. In'the pipe 136, is avalve 165 for controlling the flow of theliquid from the pump through the several pipes to the nozzles. This valve is operated by a rod 166, which passes through and has a bearing in the bracket 167 suitably secured to the side of the barrel, and at its upper end having a handle 168 within the reach of the operator from his seat.

As seen in Fig. 3, I also employ a float, preferably a metallic drum 169, secured to which isa rod 170 passing through an eye 171 and the bracket 172, secured as indicated at 173 inone head of the barrel, and this rod 170 preferably extends through a hole 174 in the top of the barrel so as to indicate when the barrel is empty, it being under stood that the height to which the float can risein the barrel is determined by the positionof the bracket 17 2, and this also determines the extent to which the rod 170 may protrude from the upper, surface of the barrel. And furthermore, as will beapparent, whenthe barrel is empty or approximately so, this condition will be indicated by the position of the end of the rod, which, un-

der these circumstances, is that shown in Fig. 3.

In the operation of thehereinbefore de-,

and forced into the air chamber 71, and

thence through the pipe 136 through the pipes leading therefrom to the several nozzles. The height of the nozzles may be ad-- justed bythe hangers 115 and 140, the lateral position of which may be controlled by the operator through the foot piece 108, the rods 110 and 111, the levers 126 and 148, and the connecting rods 130 and 152. Also, as hereinbefore described, the pairs of nozzles are adjustable laterally of the machine on the ends 113 and 138 of the arms 112 and 137, and furthermore the distance between the noz-' zles of each pair maybe adjusted by fixing the same in the openings in the ends of the support bars 122 and 145, in which these pairs of nozzles respectively are connected through the levers to which the same are pivotally connected.

The flow of the liquid from the pump to the nozzles is controlled by the valve 165, and the pressure of the liquid at the nozzles is governed by'the adjustment of the relief valve 78. Still furthermore, the height of the liquid in the barrel is indicated by the position of the rod 17 0, which, as hereinbe fore described, is controlled by the float 169.
